Abstract

MECANISMO QUE TRADUCE EL GIRO DE UN DISCO DE MARCACION TELEFONICA EN UN TREN DE IMPULSOS POR APERTURAS SUCESIVAS DE UN CONTACTO ELECTRICO, APARECIENDO EL PRIMER IMPULSO TRAS UN GIRO DEL DISCO DOBLE DEL INTERVALO ENTRE IMPULSOS. EL CONTACTO (A) SE REALIZA ENTRE DOS RESORTES. EL SUPERIOR, CORTO, LLEVA UNA LENGUETA (B) SOBRE LA QUE GIRA LA EXCENTRICA. EL RESORTE INFERIOR ES DE MAYOR LONGITUD. EN LA POSICION INICIAL LA LEVA B EMPIEZA A GIRAR SOBRE EL TRINQUETE (C). ESTE SE VE RETENIDO AL TROPEZAR SU PROLONGACION (D) CON EL RESORTE CORTO Y SOLO LIBERADO MEDIA VUELTA DESPUES. EL TRINQUETE ES DETENIDO DESPUES POR EL RESORTE LARGO, Y MAS TARDE POR EL CORTO, PROVOCANDO POR FIN LA APERTURA DEL CONTACTO.
